Arch x86_64 won't boot, but i686 will. Live USB and HDD.

To be more succinct, what could cause 64 bit arch not to boot when 32 bit arch boots fine on a non-UEFI system that supports 64 bit, when all other variables are constant?

--
My first response seeing this post would be to immediately assume the noob (me) posting this doesn't know the difference between a 32 and 64 bit system. However, "ubuntu-14.04.1-desktop-amd64.iso" (latest 64 bit ubuntu iso) boots from live USB and installs without error. It also came preinstalled with Windows 7 (64 bit), so I'm relatively sure it supports x86_64.

I wrote "archlinux-2014.08.01-dual.iso" (MD5 verified) to my USB. Selecting i686 boots fine. Selecting x86_64 restarts my system, eventually sending me back to the arch live menu after it posts.

Upon recommendation by a WonderWoofy on reddit, I tried to install arch x86_64 by bootstrapping and chrooting from the 64 bit ubuntu live usb. I ended up with same problem, where attempting to load arch reboots my system immediately.

Right now, I'm assuming it's the same issue booting from the live usb (arch iso) and from the arch installation on my hard drive, since they seem identical to me. I haven't tried recreating the install for i686 to see if it works (mainly because it's late -- if it'll help I'll do it upon suggestion).

Here's the only text that shows once I attempt to boot into arch. This is from the hard drive and using syslinux (which is pointed at my root partition on sda -- I don't have a boot partition).

Loading ../vmlinuz-linux... ok
Loading ../initramfs-linux.img...ok
Probing EDD (edd=off to disable)... ok

Which doesn't look like it's messing up anywhere...

And of course I'm a noob so go easy on me x)

UPDATE: I found this thread but I'm not seeing his error message, so I'm not sure what to do.

"so I'm relatively sure it supports x86_64."

Just to make sure your CPU has a x86_64 architecture, why don't you check and post the output of lscpu?

Tell us what hardware you actually have.

It's an Intel Core 2 Quad processor. Are there any more diagnostic commands that would be helpful? I didn't see anything else in util-linux that might help...

Here's the output for "lscpu":

How did you write the iso to the USB stick? Did you use Unetbootin, or dd?

I actually used USBWriter 1.2 on Windows 8.1. I have a few USB drives I can use, so I can try mixing it up.
